A New Species

We describe Dinacoma sanfelipe sp. nov. from southern California, the first new species belonging to the melolonthine scarab beetle genus Dinacoma Casey, 1889 (Scarabaeidae: Melolonthinae: Melolonthini) to be described in 90 years, based upon examination of 141 specimens of that genus. Diagnostic comments, a dichotomous key, photographs of all species of Dinacoma, and a distribution map are presented to facilitate the identification of adult male specimens.  One species in the genus is federally listed under the United States Endangered Species act, and all known species may be of conservation concern. Key words: Scarabaeoidea, Melolonthini, scarab beetle, insect conservation, cryptic species

A New Species

A new Eridantes Crosby & Bishop (1933) species, E. diodontos n. sp., discovered in the United States in the state of Arizona and in Mexico in the state and city of San Luis Potosí, is described and illustrated. Both males and females are very similar to the respective sexes of the type species, E. erigonoides (Emerton 1882), but can be distinguished by the higher cephalic lobe, position of the prosomal pit, and the form of the palpal tibia in the male and by the convolution of the m-shaped carinae of the epigynum in the female. Comparative illustrations of the male bulb of E. erigonoides and a distribution map of the three known species are also provided. Pending formal taxonomic revision of Eridantes, a revised diagnosis and a brief description of the genus are presented based on examination of specimens of the type species and of the new species described here. The mesal rather than ectal position of the paracymbium and the broadly divided dorsal and ventral sclerites of the largely membranous radix are proposed synapomorphies that distinguish Eridantes from all similar genera.

A New Species

AbstractThe order Intejocerida is an enigmatic, short-lived cephalopod taxon known previously only from Early–Middle Ordovician beds of Siberia and the United States. Here we report a new genus, Cabaneroceras, and a new species, C. aznari, from Middle Ordovician strata of central Spain. This finding widens the paleogeographic range of the order toward high-paleolatitudinal areas of peri-Gondwana. A curved conch, characteristic for the new genus, was previously unknown from members of the Intejocerida.UUID: http://zoobank.org/21f0a09c-5265-4d29-824b-6b105d36b791

Species Extinctions

The United States Endangered Species Act is one of the strongest laws of any nation for preventing species extinction, but quantifying the Act’s effectiveness has proven difficult. To provide one measure of effectiveness, we identified listed species that have gone extinct and used previously developed methods to update an estimate of the number of species extinctions prevented by the Act. To date, only four species have been confirmed extinct with another 22 possibly extinct following protection. Another 71 listed species are extinct or possibly extinct, but were last seen before protections were enacted, meaning the Act’s protections never had the opportunity to save these species. In contrast, a total of 39 species have been fully recovered, including 23 in the last 10 years. We estimate the Endangered Species Act has prevented the extinction of roughly 291 species since passage in 1973, and has to date saved more than 99 percent of species under its protection.

A New Species

Pternopetalum paucifoliolatum, a new species from Sixigou Scenic Area, Emeishan City, Sichuan Province, is proposed and described. Diagnostic morphological characters, full description, detailed illustrations, and a distribution map are provided. The new species is similar to P. porphyronotum in possessing the 1-pinnate leaves and the abaxially purple-red leaflets, but differs from the latter by shorter stature, fewer leaflets ((1–) 3–7) and rays (5–8), the leaflet margin white-ciliate. The new species, which is assessed as Critically Endangered (CR), was only found on limestone cliffs. We also provide a new key to the species of Pternopetalum.

Hypericum bilgehan-bilgilii is here described and illustrated as a new species of section Triadenioides, from the Southern Anatolia, Turkey. Distribution map, habitat and ecology, etymology, the Turkish name for the new species, and dichotomous key are given. The new species is compared with morphologically close species, H. ternatum and H. pallens.

The eastern Nearctic species of the genus Soyedina Ricker, 1952 (Plecoptera: Nemouridae) are reviewed. Two morphology-based species groups are proposed based on epiproct characteristics. Soyedina sheldoni sp. nov. is described from the southern Appalachian Highland region of western North Carolina. A distribution map and a dichotomous key to all nine Nearctic species are provided.
